Sad to hear about Sims. I had a Sportsman model for years paired with my Beckel Eena wall tent but burned it out. I’m with Kifaru now too and have a Small for my SuperTarp & Medium for my 6 man Tipi but like Saddlesore said, these little tinny stoves aren’t meant for long term heat. If long term is in mind, go with something with more iron in it.
